There were still thick crusts of dirty snow piled up on the edges of the pavement outside Krasnopresnenskaya, a Metro station in central Moscow, on Tuesday. Beside this reminder of a long winter stood four young men and women holding bright green balloons. “Spring is coming!” said one of them, while handing out leaflets to passers-by.

The four, along with similar groups of activists elsewhere, are trying to mobilise their compatriots to come out in Moscow, and a handful of other Russian cities, on Sunday to protest against President Vladimir Putin in what they are calling an “anti-crisis march”.

“After years of siphoning off the oil revenues, the current regime has led the country to a standstill and into complete bankruptcy,” the leaflets say. “Putin and his government cannot lift the country out of crisis and must leave.”
